ECS-3955M SERIES SMD CLOCK OSCILLATOR
The ECS-3955M (5V) ia a high capacitive load
version of our minature, crystal controlled,
low current clock oscillator in an all ceramic
SMD package. The low profile package is
ideal for PC’s, portable applications and
PCMCIA cards.
FEATURES
• High capacitive load options
• Low power consumption
• Tri-State Function
• Seam welded package
• Tape & Reel (1,000 pcs STD)

* Inclusive of 25˚C tolerance, operating temperature range, input voltage change, load change, aging shock and vibration.
** An internal pullup resistor from pin 1 to 4 allows active output if pin 1 is left open.
Note: A 0.01 µF bypass capacitor should be placed between VCC (Pin 4) and GND (Pin 2) to minimize power line noise.
